"Steve" wrote /snip/ I think the reason I raised the question was because I got to thinking about that "Big Red Button" on my new DSC VHF, labeled "Distress" (or some word to this effect). Understand that by activating this button/switch, my VHF will automatically send my distress signal and vessel ID (MMSI) and GPS position (assuming GPS is connected). However, I'm also hearing that the USCG is not yet equipped or manned to monitor for this emergency frequency. Steve (still learning) s/v Good Intentions Hi Steve, Full coverage of VHF-DSC will not be complete until the Rescue-21system is fully implemented, and that may be another two years. But in the interim, USCG Stations and Groups have installed DSC guard-receivers that alert to all Ch-70 (Distress button) messages. This may not be complete in all areas, but it has been in effect on the East coast for over a year. This afternoon a search involving two USCG vessels working an area from the Mouth of the Chesapeake Bay out to the Atlantic-side of Virginia Beach oceanfront, lasted about two hours before being classed as an uncorrelated Mayday and suspended. Someone had pressed the Distress button on a DSC-equipped VHF radio, and no position or other information was sent. Every boater's DSC-equipped radio that was in range and operating, would have been commanded to ch-16 as an alert-tone sounded. This way, all vessels in range of the distress will be able to hear the voice mayday when (if) it comes. When the sending-radio is through with it's timed-distress signal, the operator may turn to ch-16 and make his voice call of distress. When that doesn't follow, it ties up valuable assets and personnel that are unable to assist vessels in real distress. That's the second false-DSC alert this week, and it's only Tuesday. Jack |
